	Windows-speak...

	Where UNIX/Linux relies upon the first line of a script to identify
what executable is used to process it (the #! line), Windows uses a linked
pair of registry entries


C:\Users\Wulfraed\Documents>assoc .py
.py=Python.File

C:\Users\Wulfraed\Documents>ftype python.file
python.file="C:\PYTHON~2\Python27\python.exe" "%1" %*

C:\Users\Wulfraed\Documents>


	"ftype" takes a type label and defines the command line used to execute
that file type (or otherwise open the file... ).

	"assoc" takes a file extension and "associates" it with the type label
-- allows multiple extensions to be linked to one command line

.py=Python.File
.pyc=Python.CompiledFile
.pyo=Python.CompiledFile
.pys=pysFile
.pyw=Python.NoConFile


Python.CompiledFile="C:\PYTHON~2\Python27\python.exe" "%1" %*
Python.File="C:\PYTHON~2\Python27\python.exe" "%1" %*
Python.NoConFile="C:\PYTHON~2\Python27\pythonw.exe" "%1" %*

(No idea where .pys came from -- it has no defined executor)

	These are how one can do things like

C:\Users\Wulfraed\Documents>scite t.py

C:\Users\Wulfraed\Documents>python t.py
Goodbye

C:\Users\Wulfraed\Documents>t.py
Goodbye

C:\Users\Wulfraed\Documents>t
Goodbye

	There's another environment variable that defines what order to search
extensions when not provided (as in the last sample above), as one may have
a t.py, t.bat, t.doc, etc.

PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC;.py;.pyw

Hmmm, think I need to edit that... shove the .py* behind .bat -- I don't
use the others so why have the system try to find them first. I'd add
powershell but its designed for security and pretty much needs to be
manually invoked.
